MC33348D-1-One unit intelligent battery pack lithium battery protection circuit
The MC33348 is a monolithic Li-Ion battery protection circuit designed to enhance the useful working life of a one-cell rechargeable battery pack. Cell protection features include internally fine-tuned charge discharge voltage limit, discharge current limit detection with delayed turn-off, and virtually zero current sleepmode state when cells are discharged. Another feature includes an on-chip charge pump to reduce MOSFET losses while charging or discharging low cell voltage battery packs. The protection circuit requires a minimum number of internal and external components for the included battery pack. The MC33348 is a standard SOIC 8-lead surface mount package.
• Internally trimmed charge and discharge voltage limits • Discharge delay shutdown current limit detection • Current Sleepmode near zero state when cells are healed and discharged • Low battery voltage battery drain charge pump • Dedicated for one cell application Smallest components inside • Available in low profile surface mount packages
